Peter,
Thanks so much for your helping hand!
Bavgan and Weisner,
I'm without my reference library for the Fw 190 D, so, sorry, I can't add anything about the D-9 pic.
As for the K-4 pic, it is already published în Carl Hildebrant's Broken Eagles 3: Bf 109 G/K part II, p. 16, 1988. Thanks to F19Gladiator, you can enjoy a higher resolution scan of this very same photo in the following LEMB thread, post #32:

Location of Fürth is correct.
Cheers
Marc
